Application November 6, 1935, Serial No. 48,528 I .2 claims. (on 'i2-1s)l My invention relates to building constructions.

One of the objects of my invention is to provide an improved facing for building constructions embodying theuse of a sheet of glass for the exposed face, the facing having anchorage means for securing it to a plastic support.

A further object of my invention is to provide such a construction in which the anchorage means are secured to the sheet of glass by the fusion ofa layer of colored vitriflable material.

A further object is to provide such a construction in which the coloring material will be protected.

A further object is to provide such a construction in which the facing will be securely anchored to the support.

A further object is to provide such a construction which will be inexpensive to manufacture' tion will be apparent from the description andl claims.

In the drawing, in which my invention is illustrated,

Figure 1 is a sectional view of a glass panel provided on its rear surface with a layer of colored vitriflable material and anchorage means; and i Fig. 2 is a sectional view showing a somewhat different form of construction.

Referring to the drawing in detail and to then be nely ground and mixed with suitable fluxes and coloring materials and then applied by wet process, 4as by means of a brush, spray gun, or screening process. By wet process is meant holding the enamel in suspension with Water, alcohol, or oils, ora combination of these liquids.

The anchorage material 3, which may be a grit -coating consisting of finely-ground, light fire clay,

may then be sieved upon the coating of vitriable material, after which the glass panel, with the coating of vitriable material and the anchorage material, may be secured together as a unit by 4 fusion, as by inserting it into a kiln or lehr at a' suitable temperature. The'vitriable material and the sheet of glass shouldl have such fusing characteristics that thev layer of -vitriflable material' 5 will fuse-at a somewhat lower temperature than the sheet of glass, thus avoiding softening and bending of the sheet of glass. The particles of grit form. an anchorage for the panel by means of which it may be secured to any suitable plastic backing, as will be described in detail hereinafter.

It may sometimes. be desirable to provide two layers of the colored vitriflable material, the first layer being applied and fused to the sheet vof glass, and the second layer, with the anchorage material, being thereafter applied. This use of the two layers of vitriable material may be desirable when the material used is of alight color,

in which case a single layer might permit the anchorage material to settle into the layer of vitrifiable material a sumcient distance to mar the Acolor effect. In Fig. 2 is shown apanelin which two layers of colored vitrifiable material are used. In this form 'the first layer 4 of vitriable material is applied and fused to the sheet of glass substantially as described in connection with Fig. 1, except that the grit or' anchorage material is omitted. After the i'lrst layer I o f vitrilable material has been fused on, the second llayer of vitriflable material and the grit anchorage material may be applied. In .this form,

the second coating and the anchorage material may be applied in a somewhat different manner than that of Fig. 1. The frit 5 and the anchorage material 3 may be mixed together wet and then poured onto the first coating 4 of vitriflable material which has already been fused to the sheet of glass and the pane of glass with the two layers of vitriflable material and the anchorage material inserted into the kiln for the second firing. It is obvious that this method of mixing the anchorage material -and`frit together wet before application is applicable also where only one coating is applied.

In the claims where the word color is used, it is to be construed to include black and white.

Further modifications will be apparent to those skilled in the art and it is desired, therefore, that the invention be limited only by the prior art and the scope of the appended claims.

Having thus described my invention, what I claim and desire tosecure by Letters Patent is:

1. A facing tile comprising a sheet of lightpermeable glass, a thin layer of relatively opaque colored vitreous enamel glaze integrally adhered to the rear surface thereof .and interfused therewith, and anchorage material partially imbedded in said layer and protruding therefrom to provide a key for bonding the'tile to a building surface.

2. A facing tile comprising a sheet of transparent glass, a. thin 'layer of relatively opaque colored vitreous enamel glaze integrally adhered to the'rear surface thereof and interfused therewith. and anchorage material partially imbedded in said layer and-protruding therefrom to provide a key for bonding the tile to a building surface,

'said layer of vitreous enamel glazehaving a lower 5l fusing point than that of said glass sheet. v ELMER L. TORBTENSON.
